OAE
Pronunciation: O-A-E
Also written as: OAE — otoacoustic emissions
Otoacoustic emissions, sounds produced by the inner ear that are measured to assess hearing function in newborn screening.
Full Definition
Otoacoustic emissions are sounds generated by the outer hair cells in the cochlea of the inner ear in response to acoustic stimulation. These emissions can be measured using sensitive microphones placed in the ear canal and serve as an indicator of normal cochlear function. In newborn hearing screening, OAE testing is commonly used as a first-line screening tool because it is quick, non-invasive, and does not require behavioral responses from the infant. Absent or abnormal OAEs may indicate conductive or sensorineural hearing loss and require further audiological evaluation.
Usage
